ISIS has been bragging about its chemical weapons capacity for quite some time, but it is only relatively recently that the US has started to take notice of incidents in which ISIS has used a “mustard agent” against Kurdish forces across northern Iraq.

Though the attacks have caused relatively few casualties, there are an increasing number of incidents involving them, and with the US making much of deploying their “advisers” near ISIS forces, this is liable to make them convenient targets of opportunity.

The Pentagon insists that the US troops there are equipped and trained to handle being attacked by chemical munitions, but if such an incident were to happen involving US troops it would almost certainly dramatically undercut their claims that the war is going well.

The U.S. has been attempting to blame Assad for the use of chemical weapons for many months. The CIA has assisted Syrian rebels in the use of chemical weapons with the intention of blaming civilian casualties in Syria on Assad forces. On at least two occasions Syrian rebels, with backing of Western Intelligence have carried out these false flag operations and the second time nearly triggered a massive bombing campaign designed by Obama and Kerry. The first operation was uncovered by the UN and directly linked to the Syrian rebels. The second operation ended in the death of many of the rebels who were tasked with carrying it out, when the poorly trained operatives miss handled the chemical weapons. Their deaths led to the exposure of the program and its ultimate demise as the trigger for another massive U.S. intervention in the Middle East.
